Abstract: Azure B is a Phenothiazine class of dye in which an atom of sulphur
replacing oxygen in heterocyclic ring. They have color range from green to blue
and have been used for coloring paper, tannin mordant cotton, silk and leather.
The decoloration and mineralization of the Azure B dye under condition of visible
light and TiO2 photocatalyst was studied. The textile waste-water
from dyeing process normally contains considerable amount of chloride and
carbonate ions. These chemicals are often used in textile processing operations
for adjusting the PH of the dye bath It is a important to study the
effect of chloride and carbonates on the treatment efficiency. This study
confirms that the presence of Na Cl and Na2CO3 led to
inhibition of the degradation process.
